                        Connecticut Development Authority

                            Sonics & Materials, Inc.

                                 LOAN AGREEMENT

            THIS LOAN AGREEMENT, made and dated as of December 1, 1997, by and
between the Connecticut Development Authority, a body corporate and politic
constituting a public instrumentality and political subdivision of the State of
Connecticut, and Sonics & Materials, Inc., a corporation organized and existing
under the laws of the State of Delaware.

                                WITNESSETH THAT:

            WHEREAS, the State Commerce Act, constituting Connecticut General
Statutes, Sections 32-1a through 32-23xx, as amended (the "Act"), declares that
there is a continuing need in the State (1) for industrial development and
activity to provide and maintain employment and tax revenues and to control,
abate and prevent pollution to protect the public health and safety, (2) for the
development of recreation facilities to promote tourism, provide and maintain
employment and tax revenues, and promote the public welfare, (3) for the
development of commercial and retail sales and service facilities in urban areas
to provide and maintain construction and permanent employment and tax revenues,
to improve conditions of deteriorated physical development, slow economic growth
and eroded financial health of the public and private sectors in urban areas and
to revitalize the economy of urban areas, and (4) for assistance to public
service businesses providing transportation and utility services in the State,
and that the availability of financial assistance and suitable facilities are
important inducements to industrial and commercial enterprises to remain or
locate in the State and to provide industrial, recreation, urban and public
service projects; and

            WHEREAS, the Act provides that (1) the term "project" as used
therein means any facility, plant, works, system, building, structure, utility,
fixture or other real property improvement located in the State, and the land on
which it is located or which is reasonably necessary in connection therewith,
which is of a nature or which is to be used or occupied by any person for
purposes which would constitute it as an industrial project, recreation project,
urban project, public service project or health care project, and any real
property improvement reasonably related thereto, and (2) that a project may also
include or consist exclusively of machinery, equipment or fixtures; and

            WHEREAS, the Act provides that the Authority shall have power (i) to
determine the location and character of, and to extend credit or make loans to
any person for the planning, designing, acquiring, improving and equipping of a
project, which may be
<PAGE>

secured by loan, lease or sale agreements, contracts and other instruments, upon
such terms and conditions as the Authority shall determine to be reasonable,
(ii) to require the inclusion in any contract, loan agreement or other
instrument such provisions for the construction, use, operation, maintenance and
financing of the project as the Authority may deem necessary or desirable, (iii)
to issue its bonds for such purposes, subject to the approval of the Treasurer
of the State, and, (iv) to enter into agreements with prospective mortgagees and
mortgagors, and as security for the payment of the principal or redemption
price, if any, of and interest on any such bonds, to pledge or assign such a
loan, lease or sale agreement and the revenues and receipts derived by the
Authority from such a project; and

            WHEREAS, by resolution adopted June 18, 1997 in furtherance of the
purposes of the Act, the Authority has accepted the application of Sonics &
Materials, Inc. (the "Borrower") for assistance in the financing of certain
capital projects for the benefit of the Borrower and the acquisition and
installation therein of machinery and equipment related thereto, all to be used
for a manufacturing facility located in the Town of Newtown, Connecticut; and

            WHEREAS, the Authority has by resolution adopted November 19, 1997
authorized the issuance of $3,810,000 principal amount of its Industrial
Development Revenue Bonds (Sonics & Materials, Inc. Project) 1997 Series (the
"Initial Bonds") for the purpose of refinancing the Bridge Loan Note which was
used to provide funds for the financing of certain capital projects for the
benefit of the Borrower, and paying necessary expenses incidental thereto, and
financing and refinancing certain additional capital projects for the benefit of
the Borrower; and

            WHEREAS, pursuant to such resolution the Initial Bonds are to be
secured by an Indenture of Trust of even date herewith, by and between the
Authority and Brown Brothers Harriman Trust Company, as Trustee, and are also to
be secured by the Open-End Mortgage Deed, dated as of December 1, 1997, (the
"Mortgage") from the Borrower to the Authority (and assigned by the Authority to
the Trustee) and by the Security Agreement, dated as of December 1, 1997 from
the Borrower to the Authority (and assigned by the Authority to the Trustee);
and

            WHEREAS, additional funds may be necessary to repair, relocate,
rebuild or restore the Project following damage, destruction, taking or
condemnation thereof or to provide extensions, additions, improvements or
facilities to the Project and provision is made in the Indenture for the
issuance from time to time of Additional Bonds on a parity with the Initial
Bonds; and

            WHEREAS, the Initial Bonds and any Additional Bonds shall be special
obligations of the Authority, payable solely from the revenues or other
receipts, funds or moneys to be derived by the


                                       -2-
<PAGE>

Authority under this Agreement, the Mortgage, the Security Agreement or the
Indenture and from any amounts otherwise available under the Indenture for the
payment of the Initial Bonds; and

            WHEREAS, the Authority proposes with the proceeds of the Initial
Bonds to make a loan to the Borrower and the Borrower proposes to borrow such
proceeds from the Authority for the purpose of financing a portion of the cost
of undertaking and completing the Project upon the terms and conditions herein
set forth; and

            WHEREAS, the Borrower acknowledges that the Authority is providing
financing for the Project in furtherance of the Authority's corporate purposes
under the Act, that the accomplishment of these purposes is dependent upon the
compliance of the Borrower with its covenants contained in this Agreement and
contained in the Mortgage and the Security Agreement, that the Authority has a
resulting beneficial interest in the Project, and that the Borrower's use of and
interest in the Project as provided hereby are in furtherance of the discharge
of a public purpose;

            NOW, THEREFORE, in consideration of the premises and of the mutual
representations, covenants and agreements herein set forth, the Authority and
the Borrower, each binding itself, its successors and assigns, do mutually
promise, covenant and agree as follows (provided that in the performance of the
agreements of the Authority herein contained, any obligation it may incur for
the payment of money shall not be an obligation, debt or liability of the State
or any municipality thereof and neither the State nor any municipality thereof
shall be liable on any obligation so incurred, but any such obligation shall be
payable solely out of the revenues or other receipts, funds or moneys to be
derived by the Authority under this Agreement, the Mortgage, the Security
Agreement or the Indenture and from any amounts otherwise available under the
Indenture for the payment of the Initial Bonds):

      and no condition exists which, upon the execution and delivery of any
      Financing Documents, constitutes an Event of Default hereunder or an event
      of default thereunder or, but for the lapse of time or the giving of
      notice, would constitute an Event of Default hereunder or an event of
      default thereunder.

            (4) There is no action or proceeding pending or, to the knowledge of
      the Borrower, threatened against the Borrower before any court,
      administrative agency or arbitration board that may materially and
      adversely affect the ability of the Borrower to perform its obligations
      under the Financing Documents and all authorizations, consents and
      approvals of governmental bodies or agencies required in connection with
      the execution and delivery of the Financing Documents and in connection
      with the performance of the Borrower's obligations hereunder or thereunder
      have been obtained, except for such authorizations, consents or approvals
      that can only be attained after the commencement of, or the completion of,
      the Project.

            (5) The execution, delivery and performance of the Financing
      Documents and any other instrument delivered by the Borrower pursuant to
      the terms hereof or thereof are within the corporate powers of the
      Borrower and have been duly authorized and approved by the board of
      directors of the Borrower and are not in contravention of law or of the
      Borrower's certificate of incorporation or by-laws, as amended to date, or
      of any undertaking or agreement to which the Borrower is a party or by
      which it is bound.

            (6) The Borrower represents that it has not made any commitment or
      taken any action which will result in a valid claim for any finders' or
      similar fees or


                                      -16-
<PAGE>

      commitments in respect of the transactions described in this Agreement.

            (7) The Project is included within the definition of a "project" in
      the Act, and its estimated cost is equal to or in excess of $3,810,000.
      The Borrower intends the Project to be and to continue to be an authorized
      project under the Act during the Term.

            (8) All amounts shown in Schedule D-1 of the Tax Regulatory
      Agreement are eligible costs of a project financed by bonds issued by the
      Authority under the Act, and may be financed by amounts in the Project
      Fund under the Indenture. None of the proceeds of the Bonds will be used
      directly or indirectly as working capital or to finance inventory.

            (9) The Project is in material compliance with all applicable
      federal, State and local laws and ordinances (including rules and
      regulations) relating to zoning, building, safety and environmental
      quality. The Borrower intends to proceed with due diligence to complete
      the Project pursuant to Section 4.1 hereof.

            (10) The availability of financial assistance from the Authority as
      provided herein and in the Indenture has induced the Borrower to locate
      the Project in the State. The Borrower does not intend to lease the
      Project, except in the ordinary course of business of the Borrower.

            (11) The Borrower will not take or omit to take any action which
      action or omission will in any way cause the proceeds of the Bonds to be
      applied in a manner contrary to that provided in the Indenture and the
      Financing Documents as in force from time to time.

            (12) The Borrower has not taken and will not take any action and
      knows of no action that any other person, firm or corporation has taken or
      intends to take, which would cause interest on the Bonds to be includable
      in the gross income of the recipients thereof for federal income tax
      purposes. The representations, certifications and statements of reasonable
      expectation made by the Borrower in the Tax Regulatory Agreement, dated
      the date of delivery hereof and relating to the Project description,
      composite issues, bond maturity and average asset economic life, use of
      Bond proceeds, arbitrage and related matters are hereby incorporated by
      this reference as though fully set forth herein.

            (13) The Borrower has good and marketable title in fee simple to the
      Project Realty, subject only to


                                      -17-
<PAGE>

      Permitted Encumbrances, sufficient for the purposes of this Agreement.

            (14) The Borrower has obtained a standard American Land Title
      Association ("ALTA") title insurance policy from a title insurance company
      satisfactory to the Trustee in an amount at least equal to the face amount
      of the Initial Bond (or such lesser amount as shall be approved by the
      Original Purchaser) insuring the Authority and the Trustee on behalf of
      the Bondholders as their respective interests may appear, and containing
      only such exceptions as have been approved by an Authorized Representative
      of the Authority and the Trustee.

            (15) The Borrower has good and merchantable title to the Project
      Equipment owned by the Borrower as of the date hereof, free and clear of
      liens and encumbrances except for Permitted Encumbrances.

            (16) As of the date hereof, neither the Borrower, nor to its
      knowledge anyone acting on behalf of the Borrower, has entered into
      negotiations with any person for the purpose of undertaking any borrowing
      concurrently with or subsequent to the issuance of the Initial Bonds and
      to be secured wholly or partially by a lien or encumbrance on the Project
      or any part thereof, and the Borrower has no present intention of
      undertaking any such borrowing, except in connection with the requirements
      described in the Borrower's application to the Authority.

            (17) The representations of the Borrower set forth in the Tax
      Regulatory Agreement delivered concurrently with the execution and
      delivery hereof are by this reference incorporated in this Agreement as
      though fully set forth herein.

                                    THE LOAN

            Section 3.1. Loan Clauses. (A) Subject to the conditions and in
accordance with the terms of this Agreement, the Authority agrees to make a loan
to the Borrower from the proceeds of the Initial Bonds in the amount of
$3,810,000 and the Borrower agrees to borrow such amount from the Authority.

            (B) The loan shall be made at the time of delivery of the Initial
Bonds and receipt of payment therefor by the Authority against receipt by the
Authority of the initial Note duly executed and delivered to evidence the
pecuniary indebtedness of the Borrower hereunder. Any additional loan shall be
made at the time of delivery of the applicable series of Additional Bonds and
receipt of payment therefor by the Authority against receipt by the Authority of
a supplemental Note duly executed and delivered to evidence the additional
pecuniary indebtedness of the Borrower hereunder. As and for the loan the
Authority shall deposit the proceeds of the Initial Bonds into the Debt Service
Fund and the Project Fund as provided in the Indenture and such proceeds shall
be held, and invested and disbursed as provided in the Indenture on the terms
and conditions therein prescribed.

            (C) On or before each due date for the payment of the principal of
or interest on the Bonds, until the principal or Redemption Price, if any, of
and interest on the Bonds shall have been fully paid or provision for the
payment thereof shall have been made in accordance with the Indenture, the
Borrower shall make loan payments to the Trustee for the account of the
Authority in an amount which, when added to any moneys then on deposit in the
Debt Service Fund and available therefor, shall be equal to the amount payable
on such due date with respect to the Bonds as provided in Section 5.3 of the
Indenture, including amounts due for the payment of the principal of and
interest on the Bonds. In addition, the Borrower shall pay to the Trustee, as
and when the same shall become due, all other amounts due under the Financing
Documents, together with interest thereon at the then applicable rate as set
forth herein. The Borrower shall have the option to prepay its loan obligation
in whole or in part at the times and in the manner provided in Article VIII
hereof.

            (D) [Reserved]

            (E) Anything herein to the contrary notwithstanding, any amount at
any time held in the Principal and Interest Account of the Debt Service Fund by
the Trustee pursuant to this Section shall be credited against the next
succeeding loan payment obligation of the Borrower as provided in subsection
3.1(C) hereof. If, on any due date for payments with respect to the Bonds, the
balance in the Debt Service Fund is insufficient to make such payments, the


                                      -19-
<PAGE>

Borrower agrees forthwith to pay the amount of the deficiency. If at any time
the amount held by the Trustee in the Debt Service Fund shall be sufficient to
pay or provide for the payment of the Bonds in accordance with Section 12.1 of
the Indenture, the Borrower shall not be obligated to make any further payments
under the foregoing provisions.

            Section 3.2. Other Amounts Payable. (A) The Borrower hereby further
expressly agrees to pay to the Trustee as and when the same shall become due,
(i) an amount, as may be agreed upon from time to time between the Borrower and
the Trustee and/or the Paying Agent, equal to the initial and annual fees of the
Trustee for the ordinary services of the Trustee rendered and its ordinary
expenses incurred under the Indenture, including fees and expenses as registrar
and in connection with the preparation of new Bonds upon exchanges or transfers,
and the fees and expenses of the Trustee and any Paying Agents on the Bonds for
acting as paying agents as provided in the Indenture, including the reasonable
fees and expenses of its counsel and (ii) the reasonable fees and expenses of
the Trustee for extraordinary services rendered by it and extraordinary expenses
incurred by it under the Indenture, including reasonable counsel fees and
expenses (iii) the reasonable fees and expenses of the Authority, including the
reasonable fees and expenses of its counsel, incurred by the Authority as a
result of an Event of Default or otherwise enforcing this Agreement, (iv) the
reasonable fees and expenses of the Bondholder as a result of an Event of
Default or otherwise enforcing this Agreement and for any consent, waiver or
amendment relating to the Indenture or any of the Financing Documents, including
reasonable fees and expenses of counsel for such Bondholders, and (v) any other
sums required to be paid by the Borrower under the terms of the Indenture and
the Note.

            (B) The Borrower also agrees to pay all amounts payable by it under
the Tax Regulatory Agreement, including any expenses of the Authority incurred
in connection with rebate compliance pursuant to the Tax Regulatory Agreement,
and the Financing Documents at the time and in the manner therein provided.

            (C) The Borrower also agrees to fund, replenish and maintain all
amounts required to be funded, replenished and maintained in the Funds and
Accounts established in and as required by Article V of the Indenture.

            (D) The Borrower also agrees to pay directly to the Authority on the
date of issuance of the Bonds a fee equal to 1/2 of 1% of the principal amount
of the Initial Bonds, such fee to be payable, without notice, demand or invoice
of any kind at the Authority's address as set forth herein or at such other
address and to the attention of such other person, or to such account as the
Authority may stipulate by written notice to the Borrower.


                                      -20-
<PAGE>

            (E) The Borrower also agrees to perform all obligations required to
be performed by it under the Indenture in accordance with its terms.

            (F) The Borrower also agrees to pay, or cause to be paid, when due,
any amounts necessary to redeem Bonds which have been called for redemption
under the Indenture (including, if any applicable premiums thereon).

            Section 3.3. Manner of Payment. The payments provided for in Section
3.1 hereof shall be made by any reasonable method providing immediately
available funds at the time and place of payment directly to the Trustee for the
account of the Authority and shall be deposited in the Debt Service Fund. The
additional payments provided for in Section 3.2 shall be made in the same manner
directly to the entitled party or to the Trustee for its own use or disbursement
to the Paying Agents, as the case may be.

            Section 3.4. Direct Payment to Original Purchaser. Notwithstanding
the provisions of this Loan Agreement to the contrary, so long as the Original
Purchaser is the owner of the Initial Bonds, the Borrower shall pay that portion
of the loan payments relating to the principal and redemption price of, and
interest on, the Initial Bonds directly to the Original Purchaser as provided in
Section 2.3(F) of the Indenture. In the event that the Borrower shall fail to
pay any installment of the loan payments so payable to the Original Purchaser in
accordance with this Section, interest on such overdue payment shall accrue from
the due date thereof at a rate equal to the Taxable Rate (as defined in the
Indenture).

            Section 3.5. Obligation Unconditional. The obligations of the
Borrower under the Financing Documents shall be absolute and unconditional,
irrespective of any defense or any rights of setoff, recoupment or counterclaim
it might otherwise have against the Authority or the Trustee. The Borrower will
not suspend or discontinue any such payment or terminate this Agreement (other
than in the manner provided for hereunder) for any cause, including, without
limiting the generality of the foregoing, any acts or circumstances that may
constitute failure of consideration, failure of title, or commercial frustration
of purpose, or any damage to or destruction of the Project, or the taking by
eminent domain of title to or the right of temporary use of all or any part of
the Project, or any change in the tax or other laws of the United States, the
State or any political subdivision of either thereof, or any failure of the
Authority or the Trustee to perform and observe any agreement or covenant,
whether expressed or implied, or any duty, liability or obligation arising out
of or connected with the Financing Documents.

            Section 3.6. Security Clauses. (A) The Authority hereby notifies the
Borrower and the Borrower acknowledges that, among other things, the Borrower's
loan payments and all of the


                                      -21-
<PAGE>

Authority's right, title and interest under the Financing Documents to which it
is a party (except its rights under Sections 6.2, 6.4 and 7.3 hereof) are being
concurrently with the execution and delivery hereof endorsed, pledged and
assigned without recourse by the Authority to the Trustee as security for the
Bonds as provided in the Indenture.

            (B) In order to further secure its loan obligation hereunder, the
Borrower has executed and delivered to the Authority and the Original Purchaser
the Mortgage and the Security Agreement. The Borrower hereby acknowledges and
consents to the assignment thereof to the Trustee as security for the payment of
the Bonds according to their tenor and effect.

            (C) From time to time, at the request of the Authority or the
Trustee, the Borrower shall obtain, execute and deliver one or more financing
statements and other instruments, and shall do all other acts and things, as the
Authority or the Trustee deems necessary or desirable in order to fully secure
its interest in Project Equipment acquired after the date hereof and to
effectuate the transactions contemplated hereby.

            (D) The Authority and the Borrower acknowledge that buildings or
improvements on the Project Realty are in the process of construction or repair
or are to be erected or repaired, that the Authority has agreed to make the
proceeds of the Bonds available to the Borrower in installments as the work
progresses and to pay over any balance of the proceeds remaining upon the
completion of the Project in accordance with Section 5.2 of the Indenture and
that the Borrower has agreed to complete the erection or repair of the buildings
and improvements to the satisfaction of the Authority in accordance with Article
IV hereof.

            This Agreement shall constitute a security agreement within the
meaning of the Connecticut Uniform Commercial Code. In addition to all other
rights and remedies hereunder, the Authority and the Trustee as its assignee
shall have all rights and remedies of a secured party under the Connecticut
Uniform Commercial Code.

            Section 3.7. Issuance of Initial Bonds. The Authority has
concurrently with the execution and delivery hereof sold and delivered the
Initial Bonds under and pursuant to a resolution adopted by the Authority on
November 19, 1997, authorizing their issuance under and pursuant to the
Indenture. The proceeds of sale of the Initial Bonds shall be applied as
provided in Articles IV and V of the Indenture.

            Section 3.8. Issuance of Additional Bonds. (A) If the Borrower is
not in default hereunder or under the Financing Documents, the Authority may, on
written request of an Authorized Representative of the Borrower (but, if the
Original Purchaser is the Owner of any Bonds Outstanding under the Indenture,
only with the written consent of the Original Purchaser), from time to time,


                                      -22-
<PAGE>

in its absolute discretion issue Additional Bonds on a parity with the Initial
Bonds in aggregate amounts as requested by the Borrower, but only for the
purposes and upon the terms and conditions stated herein, in the Indenture and
in the Act. Additional Bonds shall be issued only for the purposes described in
Section 2.7 of the Indenture. In each case, the costs of the issuance and sale
of the Additional Bonds and capitalized interest for such period and other costs
reasonably related to the financing as shall be agreed upon by the Borrower and
the Authority may be included in the cost thereof.

            (B) No Additional Bonds shall be issued unless (1) the terms of such
Additional Bonds, the purchase price to be paid therefor and the manner in which
the proceeds therefrom are to be disbursed shall have been approved in writing
by the Borrower and the Authority, (2) the Borrower and the Authority shall have
entered into a supplement to the Financing Documents reaffirming the
representations and covenants of the Authority and the Borrower therein
contained, describing the completion, restoration, additions, extensions,
improvements or facilities to be acquired and constructed or performed and
making provisions for the conveyance, transfer and securing of such real
property or interests therein as may be necessary or required therefor, and
adjusting the aggregate amount payable hereunder and under the Note to an amount
sufficient to pay, as and when the same matures and becomes due, the principal

amounts due under the Financing Documents, and (3) the Authority and the Trustee
shall have entered into a Supplemental Indenture authorizing the issuance of
such Additional Bonds and setting forth the terms thereof and describing or
otherwise identifying any real or personal property to be secured by the
Indenture in connection with the issuance of such Additional Bonds, and the
Authority shall have otherwise complied with the provisions of the Indenture and
the Act with respect to the issuance of such Additional Bonds.

            Section 3.9. Effective Date and Term. (A) This Agreement shall
become effective upon its execution and delivery by the parties hereto, shall
remain in full force from such date and, subject to the provisions hereof
(including particularly Articles VII and VIII), shall expire on such date as the
Indenture shall be discharged and satisfied in accordance with the provisions of
subsection 12.1(A) thereof. The Borrower's obligations under Sections 6.2, 6.4
and 7.3 hereof, however, shall survive the expiration of this Agreement.

            (B) Within three days of such expiration the Authority shall deliver
to the Borrower any documents and take or cause the Trustee to take, at the
expense of the Borrower, any such actions as may be necessary to effect the

            (C) The Borrower hereby agrees that in order to effectuate the
purposes of the Financing Documents, it will make, execute, acknowledge and

circumstances, either separately or in conjunction with others, to exhaust the
remedies of the Borrower against the contractor or subcontractor or supplier so
in default and against each surety for the performance of such contract.

      the Mortgaged Property or the principal of the Outstanding Bonds. No
      policy of insurance shall be so written that the proceeds thereof will
      produce less than the minimum coverage required by the preceding sentence,
      by reason of co-insurance provisions or otherwise, without the prior
      consent thereto in writing by the Trustee, except that each policy of
      insurance required hereunder may contain a loss deductible clause
      specifying such sum or sums as the Borrower may determine as the sum or
      sums to be deducted from the amount of loss resulting from particular
      perils. The Trustee shall consent to such coinsurance or other like
      reductions.

            (2) Business interruption insurance, protecting the Borrower and the
      Trustee, covering the Borrower's payments due under this Agreement and the
      salaries and expenses of key personnel and other minimum operating
      expenses required for the operation of the Mortgaged Property during such
      period or periods not less than twelve (12) months following damage or
      destruction of the Mortgaged Property by one of the hazards insured
      against by the insurance provided for in paragraph (A)(1) above.

            (3) Commencing with the date of settlement for the Initial Bonds,
      public liability insurance (including interests of the Borrower) and
      automobile liability insurance, in an occurrence form, in the minimum
      amount


                                      -27-
<PAGE>

      of $1,000,000 bodily injury and property damage combined single limit and
      aggregate where applicable.

            (4) Worker's compensation and employer's liability insurance meeting
      the Borrower's statutory obligations; provided, however, that, if the
      Borrower becomes an approved self-insured, employer's liability coverage
      in the amount of at least $100,000 shall be purchased.

            (5) Boiler and machinery coverage (direct damage and use and
      occupancy) on a replacement cost basis where deemed advisable by the
      Borrower, or where otherwise required.

            (6) Excess liability coverage in the amount of at least either
      straight excess or umbrella excess, covering excess of paragraphs (3) and
      (8) to be maintained in force so that the total coverage available under
      each of the aforementioned paragraphs, including this subsection, is not
      less $5,000,000 per occurrence and in the aggregate, where applicable, as
      excess of employer's liability, general liability, professional liability
      and automobile liability coverage.

            (B) All policies of insurance and bonds required by this Section
5.1: shall be in such amounts and shall contain such provisions as comply with
the foregoing requirements; and in every applicable case shall contain standard
mortgagee clauses; provided, however, that the Borrower shall not be required to
provide insurance coverage which, is for risks not normally covered or is in
excess of standard requirements, if any, for facilities similar in size,
location and nature to the Mortgaged Property. All policies and bonds shall
provide, so far as the same may be obtainable without the payment of additional
premium, that coverage shall not be canceled without thirty (30) days' prior
written notice to the Trustee.

            (C) All policies of insurance and bonds shall be issued by
responsible insurance or surety companies, acceptable to the Borrower, qualified
to do business in Connecticut and qualified under the laws of Connecticut to
assume risks covered by such policy or policies or bond or bonds and shall be
non-assessable.

            (D) All policies of insurance required under paragraphs (A)(1), (2),
and (5) above shall be for the benefit of the Borrower and the Trustee, as their
respective interests may appear, and shall be made payable to the Trustee. The
Trustee shall have the exclusive right after obtaining the advice and consent of
the Borrower which shall not be unreasonably withheld (and after the occurrence
of an Event of Default, without notice to or consent of the Borrower) to receive
the proceeds from such insurance and settle and receipt for claims thereunder.
Policies evidencing the insurance required by paragraphs (A)(3), (4) and (6)
above shall


                                      -28-
<PAGE>

be for the benefit of the Borrower. The Borrower shall have the right to receive
payments due and to receipt for claims under policies of insurance and fidelity
bonds required by subparagraph (A)(3), (4), and (6) above. The original or a
copy of each policy or bond or a certificate that the same has been issued and
is currently in effect shall be delivered to the Trustee.

            (E) In the event that any insurance required by this Section 5.1 is
not commercially available at a reasonable cost or has been otherwise provided,
the Trustee shall accept such substitute coverage, if any.

            (F) In the event that the Borrower fails to maintain, or cause to be
maintained, any insurance as provided in this Section 5.1, the Trustee may (but
shall be under no obligation to), upon such notice to the Borrower as is
reasonable under the circumstances, procure and maintain such insurance, and any
amounts so advanced therefor by the Trustee shall become an additional
obligation of the Borrower secured by this Agreement, which amounts, together
with interest thereon at one percent above the prime rate of the Trustee from
the date thereof, the Borrower agrees and covenants to pay.

            Section 5.2. Casualty; Condemnation; Loss of Title. If the Mortgaged
Property shall be wholly or partially destroyed or damaged by fire or other
casualty covered by insurance required under Section 5.1(A)(1) or (5), or if the
Mortgaged Property shall be wholly or partially condemned, taken or injured by
any person, including any person possessing the right to exercise the power of
or a power in the nature of eminent domain or transferred to such a person, by
way of a conveyance in lieu of the exercise of such a power by such person, or
if any part of the Mortgaged Property shall be lost because of failure of title,
the Borrower covenants that it will take all actions and will do all things
which may be necessary to enable recovery to be made upon such policies of
insurance or on account of such taking, condemnation, conveyance, damage, injury
or loss of title in order that moneys due on account of losses suffered may be
collected and paid to the Trustee. Any appraisement or adjustment of loss or
damage and any settlement or payment therefor, which may be agreed upon by the
Borrower and the appropriate insurer or condemnor or person, shall be evidenced
to the Trustee by a certificate signed by an Authorized Borrower Representative.
The Trustee may rely conclusively upon such certificate.

            Section 5.3. Proceeds of Hazard Insurance.

            (A) Immediately after the occurrence of loss or damage covered by
insurance required under Section 5.1(A)(1) or (5), the Borrower shall notify the
Authority, the Architect, and the Trustee in writing. The Architect promptly
shall determine and advise the Authority, the Trustee, and the Borrower, in
writing, whether it is practicable to repair, reconstruct or replace such
damaged or


                                      -29-
<PAGE>

destroyed or condemned or lost property and, if so, the estimated time and funds
required for such repair, reconstruction or replacement.

            (B) If the Architect shall advise that such repair, reconstruction
or replacement is practicable, and if, within ninety (90) days from the receipt
of the Architect's report (or such later date as may be reasonably acceptable to
the Trustee), the Borrower delivers to the Trustee (i) an executed construction
contract for such work at a price not greater than the amount stated in such
Architect's report and (ii) cash or an irrevocable letter of credit in an amount
equal to the funds, if any, required by such Architect's report in excess of the
available net insurance proceeds, then the Borrower shall promptly proceed to
repair, reconstruct and replace such part of the Mortgaged Property, including
all fixtures, furniture, equipment and affects, to its original condition
insofar as possible. The moneys required for such repair, reconstruction and
replacement shall be paid from: (x) the net proceeds of insurance (other than
proceeds of business interruption insurance which shall be applied as provided
in Subsection (D) below) received by reason of such occurrence, which net
proceeds (after deducting any reasonable expenses incurred by the Trustee or the
Borrower in collecting the same, the "Net Insurance Proceeds") shall be
deposited into the Project Fund and disbursed in accordance with the requisition
procedure established for the Project Fund under Section 5.2(C) of the
Indenture; and (y) to the extent such Net Insurance Proceeds are not sufficient,
from moneys to be provided by the Borrower. Notwithstanding the foregoing, if
the Architect's estimate of the cost of such repair, reconstruction or
replacement is $50,000 or less, the Borrower shall not be required to deliver
the construction contract and funds and items referred to in clauses (i) and
(ii) above, the Net Insurance Proceeds shall be paid to the Borrower and the
Borrower shall promptly proceed with such repair, reconstruction or replacement.
Any Net Insurance Proceeds remaining after the completion of such repair,
replacement or reconstruction shall be paid to the Borrower.

            (C) If the Architect advises that such repair, reconstruction or
replacement is not practicable, or not appropriate given the damaged property's
age or lack of marketability or if the Architect's report and the other
documents described in Subsection (B) above are not delivered within the
required time period, then the parties hereto agree that all respective Net
Insurance Proceeds shall be deposited in the Redemption Account and applied to
the redemption of Bonds pursuant to Section 2.4(B) of the Indenture, and the
Borrower shall pay to the Trustee prior to the redemption date any additional
amount required to effect such redemption; provided, that in the case of damage
to or destruction of all or substantially all of the Mortgaged Property, the
Borrower shall pay to the Trustee an amount sufficient, together with the Net
Insurance Proceeds, to redeem all Bonds Outstanding.


                                      -30-
<PAGE>

            (D) The proceeds of business interruption insurance required by
Section 5.1(A)(2) shall be deposited in the Debt Service Fund and applied to the
payment of the principal of and interest on the Bonds.

            Section 5.4. Eminent Domain. Immediately after the commencement of
any condemnation or similar proceedings by a third party in the exercise of a
power of eminent domain, or a power in the nature of eminent domain affecting
the Mortgaged Property the Borrower shall notify the Authority, the Trustee and
the Architect in writing.

            (A) The proceeds of any condemnation award or other compensation
paid by reason of a conveyance in lieu of the exercise of such power (after
deducting any costs or expenses incurred by the Trustee or the Borrower in
collecting the same, the "Net Condemnation Proceeds") received with respect to
all or substantially all the Mortgaged Property shall be paid to the Trustee for
deposit in the Redemption Account and applied to the redemption of all
Outstanding Bonds pursuant to Section 2.4(B) of the Indenture, and the Borrower
shall pay to the Trustee prior to the redemption date any additional amount
required to effect such redemption. Any Net Condemnation Proceeds received for a
taking of less than substantially all of the Mortgaged Property shall be applied
as provided in Subsections (B) and (C) below.

            (B) If Net Condemnation Proceeds do not exceed $500,000, and if the
Borrower certifies to the Trustee that the efficient utilization of the
Mortgaged Property has not been impaired, notwithstanding such taking, then the
Net Condemnation Proceeds shall be paid to the Borrower.

            (C) If the Net Condemnation Proceeds exceed $500,000:

            (1) The Borrower may elect to replace or restore the portion of the
      Mortgaged Property affected by such taking or conveyance, in which event
      the Borrower shall promptly proceed to replace or restore such portion of
      the Mortgaged Property, including any fixtures, furniture, equipment and
      effects, to its original usefulness and condition insofar as possible,
      provided that the Borrower has delivered to the Trustee within ninety (90)
      days of receipt of such condemnation award (or by such later date as may
      be reasonably acceptable to the Trustee) (i) a written report of the
      Architect stating such Architect's estimate of the cost of replacing or
      restoring the portion of the Mortgaged Property affected by such taking or
      conveyance, (ii) an executed construction contract for such work at a
      price not greater than the amount stated in such Architect's report and
      (iv) cash or an irrevocable letter of credit in an amount equal to the
      funds, if any, required by such Architect's report in excess of the
      available Net


                                      -31-
<PAGE>

      Condemnation Proceeds and (v) the items described in Section 4.1(J) and
      (K). The moneys required for such replacement or restoration shall be
      paid: (x) from the Net Condemnation Proceeds which shall be deposited into
      the Project Fund and disbursed in accordance with the requisition
      procedure established for the Project Fund under Section 5.2(C) of the
      Indenture; and (y) to the extent that such proceeds are not sufficient,
      from moneys to be provided by the Borrower; or

            (2) The Borrower may elect to have all or part of such Net
      Condemnation Proceeds deposited in the Redemption Account and applied by
      the Trustee to the redemption of Outstanding Bonds, and the Borrower shall
      pay any additional amount required to effect such redemption.

If the report of the Architect required by the preceding paragraph are not
delivered within the required time period, then the Net Condemnation Proceeds
shall be deposited in the Redemption Account and applied to the redemption of
all Outstanding Bonds pursuant to Section 2.4(B) of the Indenture, and the
Borrower shall pay to the Trustee prior to the redemption date any additional
amount required to effect such redemption.

            Section 5.5. Reserved.

            Section 5.6. No Abatement of Payments Hereunder. If the Project
Realty or the Project Equipment shall be damaged or either partially or totally
destroyed, or if title to or the temporary use of the whole or any part thereof
shall be taken or condemned by a competent authority for any public use or
purpose, there shall be no abatement or reduction in the amounts payable by the
Borrower hereunder and the Borrower shall continue to be obligated to make such
payments. In any such case the Borrower shall promptly give written notice
thereof to the Authority and the Trustee.

                                   ARTICLE VI

                                    COVENANTS

            Section 6.1. The Borrower to Maintain its Corporate Existence;
Exceptions Permitted. The Borrower covenants and agrees that during the Term of
this Agreement it will maintain its corporate existence, will continue to be a
corporation either organized under the laws of or duly qualified to do business
as a foreign corporation in the State and in all jurisdictions necessary in the
operation of its business, will not dissolve and will not consolidate with or
merge into another corporation or permit one or more other corporations to
consolidate with or merge into it, except as permitted in Section 6.14 hereof.

            Section 6.2. Indemnification, Payment of Expenses, and Advances. (A)
The Borrower agrees to protect, defend and hold harmless the Trustee, the Paying
Agent, the Original Purchaser (including any partner thereof), the Authority,
the State, agencies of the State, members, servants, agents, directors, officers
and employees, now or forever, of the Trustee, the Paying Agent, the Original
Purchaser, the Authority or the State (each an "Indemnified Party") from any
claim, demand, suit, action or other proceeding and from all costs, liabilities
and expenses whatsoever by any person or entity whatsoever, arising or
purportedly arising from or in connection with the Financing Documents, the
Indenture, the Bonds, or the transactions contemplated thereby or actions taken
thereunder by any person (including without limitation the filing of any
information, form or statement with the Internal Revenue Service), caused by the
negligence or wilful misconduct of Borrower, except for any wilful misconduct or
gross negligence on the part of the Indemnified Party or bad faith on the part
of any Indemnified Party other than the Authority.

            (B) The Authority, the Original Purchaser (including any partner
thereof), and the Trustee shall not be liable for any damage or injury to the
persons or property of the Borrower or its members, directors, officers, agents,
servants or employees, or any other person who may be about the Project Realty
and the Project Equipment due to any act or omission of any person other than
the Authority, the Original Purchaser or the Trustee or their respective
members, officers, agents, servants and employees.

            (C) The Borrower releases each Indemnified Party from, agrees that
no Indemnified Party shall be liable for, and agrees to hold each Indemnified
Party harmless against any attorney fees, expenses or damages incurred because
of any investigation, review or lawsuit commenced by the Trustee or Authority in
good faith with respect to the Financing Documents, the Indenture, the Bonds and
the Project Realty and the Project Equipment, and the Authority or the Trustee
shall promptly give written notice to the Borrower with respect thereto.


                                      -33-
<PAGE>

            (D) All covenants, stipulations, promises, agreements and
obligations of the Authority, the Trustee and the Original Purchaser contained
herein shall be deemed to be the covenants, stipulations, promises, agreements
and obligations of the Authority and the Trustee and not of any member,
director, officer or employee of the Authority or the Trustee in its individual
capacity, and no recourse shall be had for the payment of the Bonds or for any
claim based thereon or hereunder against any member, director, officer or
employe of the Authority or the Trustee or any natural person executing the
Bonds.

            (E) In case any action shall be brought against one or more of the
Indemnified Parties based upon any of the above and in respect of which
indemnity may be sought against the Borrower, such Indemnified Party shall
promptly notify the Borrower in writing, enclosing a copy of all papers served,
but the omission so to notify the Borrower of any such action shall not relieve
it of any liability which it may have to any Indemnified Party otherwise than
under this Section 6.2. In case any such action shall be brought against any
Indemnified Party and it shall notify the Borrower of the commencement thereof,
the Borrower shall be entitled to participate in and, to the extent that it
shall wish, to assume the defense thereof with counsel satisfactory to such
Indemnified Party, and after notice from the Borrower to such Indemnified Party
of the Borrower's election so to assume the defense thereof, the Borrower shall
not be liable to such Indemnified Party for any subsequent legal or other
expenses attributable to such defense except as provided below, other than
reasonable costs of investigation subsequently incurred by such Indemnified
Party in connection with the defense thereof. The Indemnified Party shall have
the right to employ its own counsel in any such action, but the fees and
expenses of such counsel shall be at the expense of such Indemnified Party
unless (i) the employment of counsel by such Indemnified Party has been
authorized by the Borrower, (ii) the Indemnified Party shall have reasonably
concluded that there may be a conflict of interest between the Borrower and the
Indemnified Party in the conduct of the defense of such action (in which case
the Borrower shall not have the right to direct the defense of such action on
behalf of the Indemnified Party) or (iii) the Borrower shall not in fact have
employed counsel satisfactory to the Indemnified Party to assume the defense of
such action.

            (F) The Borrower also agrees to pay all reasonable or necessary
out-of-pocket expenses of the Authority in connection with the issuance of the
Bonds, the administration of the Financing Documents and the enforcement of its
rights thereunder, including particularly any fees, charges and expenses
(including counsel fees) incurred by the Authority in connection with matters of
title, collateral security and financing and continuation statements.

            (G) In the event the Borrower fails to pay any amount or perform any
act under the Financing Documents, within ten (10)


                                      -34-
<PAGE>

Business Days following receipt of written notice, the Trustee or Authority may
pay the amount or perform the act, in which event the costs, disbursements,
expenses and reasonable counsel fees thereof, together with interest thereon
from the date the expense is paid or incurred at the prime interest rate
publicly announced from time to time by the Trustee as a commercial bank plus 2%
shall be an additional obligation hereunder payable on demand by the Authority
or the Trustee.

            (H) Any obligation of the Borrower to the Authority under this
Section shall be separate from and independent of the other obligations of the
Borrower hereunder, shall not be secured by the Financing Documents, and may be
enforced directly by the Authority or the Trustee against the Borrower
irrespective of any action taken by or on behalf of the Bondholders.

            (I) The obligations of the Borrower under this Section,
notwithstanding any other provisions contained in the Financing Documents, shall
survive the termination of this Agreement and, shall be recourse to the
Borrower, and for the enforcement thereof each Indemnified Party shall have
recourse to the general credit of the Borrower.

            Section 6.3. Incorporation of Tax Regulatory Agreement; Payments
Upon Taxability. (A) The representations warranties, covenants and statements of
expectation of the Borrower set forth in the Tax Regulatory Agreement are by
this reference incorporated in this Agreement as though fully set forth herein.

            (B) If any Bondholder receives from the Internal Revenue Service a
notice of assessment and demand for payment with respect to interest on any Bond
which when issued purported to be not subject to such assessments or demands, an
appeal may be taken by the Bondholder at the option of either the Bondholder or
the Borrower. In either case all expenses of the appeal including reasonable
counsel fees shall be paid by the Borrower, and the Bondholder and the Borrower
shall cooperate and consult with each other in all matters pertaining to any
such appeal, except that no Bondholder shall be required to disclose or furnish
any non-publicly disclosed information, including, without limitation, financial
information and tax returns. Before the taking of any appeal, however, the
Bondholder shall have the right to require the Borrower to pay the tax assessed
and conduct the appeal as a contest for reimbursement.

            (C) Not later than sixty days following a Determination of
Taxability, the Borrower shall pay to the Trustee an amount sufficient, when
added to the amount then in the Debt Service Fund and available for such
purpose, to retire and redeem all Bonds then Outstanding, in accordance with
Section 2.4 of the Indenture.

            (D) In the event that any Bonds are paid at maturity, or in the
event any Bonds are purchased by the Borrower, or purchased


                                      -35-
<PAGE>

by the Trustee pursuant to subsection 5.3(E) of the Indenture, or in the event
any Bonds are redeemed by application of Scheduled Payments or otherwise
subsequent to the Tax Incidence Date without the Bondholder entitled thereto
receiving payment of an amount at least equal to the applicable Redemption Price
thereof, plus accrued interest to the redemption date at the rate applicable
following a Determination of Taxability, and other amounts required to be paid
hereunder, the Borrower shall, promptly upon receipt from the Trustee of a
notice to that effect, pay to the Trustee for payment to the former Bondholders
entitled thereto an amount equal to the difference between the amount actually
applied to the payment, purchase or redemption of such Bonds and the applicable
Redemption Price thereof, plus accrued interest to the redemption date at the
rate applicable following a Determination of Taxability, and other amounts
required to be paid hereunder.

            (E) The obligation of the Borrower to make the payments provided for
in this Section shall be absolute and unconditional, and the failure of the
Authority or the Trustee to execute or deliver or cause to be delivered any
documents or to take any action required under this Agreement or otherwise shall
not relieve the Borrower of its obligation under this Section. Notwithstanding
any other provision of this Agreement or the Indenture, the Borrower's
obligations under this Section shall survive the termination of this Agreement
and the Indenture.

            (F) The occurrence of a Determination of Taxability shall not
constitute an Event of Default hereunder but shall require only the performance
of the obligations of the Borrower stated in this Section, the breach of which
shall constitute an Event of Default as provided in Section 7.1 hereof.

            Section 6.4. Public Purpose Covenants. (A) The Borrower covenants
that it will complete the Project in accordance with Section 4.1 hereof, and
that it will operate the Project Realty and the Project Equipment for the
purposes and in a manner consistent with the Borrower's application for
assistance to the Authority. The Borrower further covenants and agrees that it
will, throughout the term of this Agreement, (1) comply with all applicable
laws, regulations, ordinances, rules, and orders relating to the Project Realty
or the Project Equipment as provided in the Financing Documents, (2) maintain
and insure the Project Realty or the Project Equipment and pay all taxes,
payments-in-lieu-of-taxes, assessments and other governmental charges in
accordance with the Financing Documents, (3) not cause or permit the Project
Realty or the Project Equipment to become or remain a public nuisance, (4) not
allow any change in the nature of the occupancy, use or operation of the Project
Realty or the Project Equipment which is substantially inconsistent with the
Borrower's application for assistance to the Authority, except that the Borrower
may after notice to the Authority permit any such change which does not
disqualify the Project as an authorized project under the Act as in effect on
the date hereof and (5)


                                      -36-
<PAGE>

except as otherwise provided herein, not sell, assign, convey, lease or
otherwise dispose of its interest in the Project Realty or the Project Equipment
without the prior written consent of the Authority. Nothing in this Section is
intended to require the Borrower to operate the Project Realty or the Project
Equipment in such manner as, in the good faith judgment of the Borrower, shall
materially and adversely impair the operating results of the Borrower in
connection with the use of the Project Realty or the Project Equipment.

            (B) A breach of any covenant contained in this Section 6.4 shall
constitute an Event of Default, but shall permit only the exercise by the
Authority of the remedies provided in Section 7.3 hereof.

            (C) The obligations of the Borrower under this Section, and all
others contained in the Financing Documents, shall be recourse to the Borrower,
and for the enforcement thereof the Authority shall have recourse to the general
credit of the Borrower.

            Section 6.5. Further Assurances and Corrective Instruments. The
Authority and the Borrower agree that they will, from time to time, execute,
acknowledge and deliver, or cause to be executed, acknowledged and delivered,
such supplements hereto and such further instruments as may reasonably be
required for correcting any inadequate or incorrect description of the Project
Realty or the Project Equipment or for carrying out the intention of or
facilitating the performance of this Agreement, provided that no such supplement
or instrument shall alter Borrower's rights or obligations under the Financing
Documents.

            Section 6.6. Covenant by Borrower as to Compliance with Indenture.
The Borrower covenants and agrees that it will comply with the provisions of the
Indenture with respect to the Borrower and that the Trustee and the Bondholders
shall have the power and authority provided in the Indenture. The Borrower
further agrees to aid in the furnishing to the Authority or the Trustee of
opinions that may be required under the Indenture. The Borrower covenants and
agrees that the Trustee shall be entitled to and shall have all the rights,
including the right to enforce against the Borrower the provisions of the
Financing Documents, pertaining to the Trustee notwithstanding the fact that the
Trustee is not a party to the Financing Documents. The Borrower has also
reviewed the Indenture and the forms of the Bonds and the Borrower hereby
approves the forms of the Indenture and the Bonds.

            Section 6.7. Assignment of Agreement or Note. (A) The Borrower may
not assign its rights, interests or obligations hereunder or under the Note.

            (B) The Authority agrees that it will not assign or transfer any of
the Financing Documents or the revenues and other


                                      -37-
<PAGE>

receipts, funds and moneys to be received thereunder during the Term except to
the Trustee as provided in this Agreement and the Indenture.

            Section 6.8. Inspection. The Authority, the Trustee and their duly
authorized agents shall have (1) the right at all reasonable times upon
reasonable notice to enter upon and to examine and inspect the Project Realty
and the Project Equipment and (2) such rights of access thereto as may be
reasonably necessary for the proper maintenance and repair thereof in the event
of failure by the Borrower to perform its obligations under this Agreement. The
Authority and the Trustee shall also be permitted, at all reasonable times, to
examine the books and records of the Borrower with respect to the Project Realty

            Section 6.17. Reserved.

            Section 6.18. Maintenance of Mortgaged Property. (A) The Borrower
covenants that it will maintain the Mortgaged Property in good repair, working
order and condition and will from time to time make or cause to be made all
necessary and proper repairs, replacements and renewals. The Mortgaged Property
and any use thereof by the Borrower shall conform in all material respects with
all applicable zoning, planning, building, environmental protection, sanitary,
safety and other laws, rules and regulations of governmental authorities having
jurisdiction over the Mortgaged Property, and the Borrower shall not permit a
nuisance thereon; but it shall not be a breach of this Section if the Borrower
fails to


                                      -43-
<PAGE>

comply with such laws, rules and regulations during any period in which the
Borrower shall in good faith be diligently contesting the validity thereof.
Subject to the foregoing, the Borrower may at its cost remodel or make
substitutions, modifications and improvements to the Mortgaged Property as it
deems desirable for its use and purposes and the same shall be the property of
the Borrower and be included as part of the Mortgaged Property and the Project.

            (B) The Borrower agrees that all repairs, renewals, replacements,
improvements, additions and extensions, extraordinary repairs, or property in
the nature thereof, which shall be made or acquired by the Borrower during the
term hereof in connection with the Mortgaged Property forthwith shall become
part of the Mortgaged Property. The Borrower agrees to execute such instruments
as may be requested, from time to time, by the Trustee to effect the foregoing.

            (C) The Borrower shall duly pay or cause to be paid all taxes and
governmental charges of any kind that may at any time be lawfully assessed or
levied against or with respect to the Mortgaged Property, all utility and other
charges incurred in the operation, maintenance, use, occupancy and upkeep of the
Mortgaged Property and all assessments and charges lawfully made by any
governmental body for public improvements that may be secured by a lien on the
Mortgaged Property. However, the Borrower may contest in good faith any such
items, assessments and other charges and, in such event, may permit the taxes,
assessments or other charges so contested to remain unpaid during any period,
including appeals, when the Borrower is in good faith contesting the same, so
long as adequate reserves have been established and enforcement of the contested
item is effectively stayed. In the event that the Borrower fails to pay any such
taxes, assessments or other charges (other than in connection with a contest
permitted by the preceding sentence), the Trustee may (but shall be under no
obligation to), upon such notice to the Borrower as is reasonable under the
circumstances, pay such amounts, and any amounts so advanced therefor by the
Trustee shall become an additional obligation of the Borrower secured by the
Financing Documents, which amounts, together with interest thereon at the prime
rate of the Trustee from the date thereof, the Borrower agrees and covenants to
pay.

            Section 6.19. Transfer or Release of Mortgaged Property. Except as
expressly permitted in this Section and except for Permitted Encumbrances, the
Borrower will not sell or transfer any part of the tangible real or personal
property included in the Mortgaged Property, except as permitted in Section
3.6(B) hereof, or create, incur, assume or permit to exist any encumbrance, lien
or charge of any kind on the Mortgaged Property.

            (A) If no Event of Default shall have happened and be continuing,
the Borrower may, from time to time:


                                      -44-
<PAGE>

            (1) grant Permitted Encumbrances with respect to any real or
      personal property included in the Mortgaged Property; or

            (2) release unnecessary existing easements, licenses, rights of way
      and other rights or privileges; or

            (3) lease or license the use of a part or parts of the Mortgaged
      Property to any person for use in performing services necessary or
      desirable for proper and economical operation and use of the Mortgaged
      Property; provided, that prior to entering into any lease or license the
      Borrower shall deliver to the Trustee an opinion of Bond Counsel that such
      lease or license will not adversely affect the exclusion from gross income
      for federal income tax purposes of interest on the Bonds; or

            (4) remove, sell or otherwise dispose of property which has been
      replaced in the ordinary course of its business; or

            (B) The Borrower covenants that the net proceeds of any sale or
other disposition made pursuant to paragraph (A)(6) or (A)(7) above shall be
applied to the replacement of the property, fixtures or equipment sold or
disposed of, or shall otherwise be reinvested in the Mortgaged Property.

            Section 6.20. Preservation of Tax-Exempt Status of Bonds.

            (A) The Borrower agrees that (i) the Project conforms to the
description contained in the Appendices hereto; (ii) it shall not take any
action or permit any circumstances within its control to arise or continue, if
such action or circumstances, or its expectation on the date of issue of the
Bonds, would cause the Bonds to be "arbitrage bonds" under the Code or cause the
interest paid by the Authority on the Bonds to be subject to Federal income tax
in the hands of the holders thereof; and (iii) it shall use its best efforts to
maintain the tax-exempt status of the Bonds.

      consecutive days.

            (7) The occurrence of an event of default under the Credit Agreement

rights hereunder, but no such waiver or determination shall extend to any

without the Trustee's or Bondowners' instituting the remedial steps provided for
in subsection 7.2(A)(1) hereof or subsection 8.1(B) of the Indenture, the
Authority may, so long as such Event of Default is continuing, send a notice to
the Trustee calling for the acceleration of all of the Borrower's obligations
under the Financing Documents and for the redemption of all of the Bonds then
Outstanding. Any such notice shall set forth in reasonable detail the default by
the Borrower giving rise thereto and shall specify the date upon which (1)
notice of Bond redemption is to be given by the Trustee (which shall be not less
than one hundred twenty days from the date of the Authority's determination
notice) and (2) the redemption of the Bonds is to occur (which shall be thirty
days after notice of redemption is given by the Trustee). Within thirty days
following receipt of the notice, the Trustee shall forward a copy thereof to the
Borrower and each registered Bondowner, together with a copy of Sections 6.4 and
7.3 of this Agreement.

            (B) If, within sixty days after the mailing of notice by the Trustee
to the Borrower and Bondowners, the Trustee receives no objection (as
hereinbelow provided) to such redemption, the Trustee shall give such notice and
effect to acceleration of the Borrower's obligations and the redemption of all
Outstanding Bonds in accordance with the Authority's notice and pursuant to
Section 2.4 of the Indenture. If, however, the Borrower or any Bondowner
disputes the existence of such Event of Default, the Borrower or such Bondowner
shall mail a notice to the Authority and the Trustee containing a statement of
such person's belief with respect to the claimed default. The receipt of such
notice by the Trustee shall serve to suspend the proceedings for redemption of
Bonds initiated by the Authority's notice of default.

            (C) If upon receipt of such notice from the Borrower or any
Bondowner, the Authority determines to affirm its earlier determination, either
the Borrower or any Bondowner shall have the right to bring an action in any
court of competent jurisdiction to enjoin the proceedings for the redemption of
the Bonds, and during the pendency of any such action the redemption proceedings
shall be suspended. Neither the Authority, the Borrower nor any Bondowner shall
be responsible for any costs, fees, expenses, or counsel fees incurred by any
other party in connection with any such action except that the Borrower shall be
responsible for the payment of the costs, fees and expenses of the Trustee and
its counsel. In the event the Authority is successful in such a proceeding, and
a final judgment is rendered which is not appealable or appealed within sixty
days thereafter finding the Borrower in default under Section 6.4 hereof, the
Trustee shall, promptly upon receipt of notice of the entry of the decision,
give notice of the redemption of all Outstanding Bonds under Section 6.4 of the
Indenture, and


                                      -48-
<PAGE>

redeem all such Bonds upon the date fixed for redemption in the notice (which
shall be thirty days after the notice is given). In the event the Borrower or
such Bondowners are successful in such a proceeding, and a final judgment is
rendered which is not appealable or appealed within sixty days thereafter
finding the Borrower not to be in default under Section 6.4 hereof, all
proceedings for the redemption of Bonds commenced under this Section shall be
terminated. No such judgment, however, shall prejudice the exercise of the
Authority's rights under this Section upon the occurrence of any subsequent
failure of performance under Section 6.4 hereof.

            (D) Within fifteen days of the date the Trustee gives notice of any
redemption of Bonds pursuant to this Section, the Borrower shall pay as a final
loan payment a sum sufficient, together with other funds on deposit with the
Trustee and available for such purpose, to redeem all Bonds then Outstanding
under the Indenture at 100% of the principal amount thereof plus accrued
interest to the redemption date. The Borrower shall also pay or provide for all
reasonable and necessary fees and expenses of the Trustee and any Paying Agent
accrued and to accrue through the date of redemption of all such Bonds.

            (E) Nothing contained in this Section shall be deemed to prevent the
Authority or the Borrower from seeking equitable relief if it asserts or
disputes, as the case may be, the existence of an event of a public purpose
default.

            Section 7.4. No Duty to Mitigate Damages. Unless otherwise required
by law, neither the Authority, the Trustee nor any Bondholder shall be obligated
to do any act whatsoever or exercise any diligence whatsoever to mitigate the
damages to the Borrower if an Event of Default shall occur.

            Section 7.5. Remedies Cumulative. No remedy herein conferred upon or
reserved to the Authority or the Trustee is intended to be exclusive of any
other available remedy or remedies but each and every such remedy shall be
cumulative and shall be in addition to every remedy given under this Agreement
or now or hereafter existing at law or in equity or by statute. Delay or
omission to exercise any right or power accruing upon any default or failure by
the Authority or the Trustee to insist upon the strict performance of any of the
covenants and agreements herein set forth or to exercise any rights or remedies
upon default by the Borrower hereunder shall not impair any such right or power
or be considered or taken as a waiver or relinquishment for the future of the
right to insist upon and to enforce, by injunction or other appropriate legal or
equitable remedy, strict compliance by the Borrower with all of the covenants
and conditions hereof, or of the right to exercise any such rights or remedies,
if such default by the Borrower be continued or repeated.

                                 PROMISSORY NOTE

No. 1                                                                 $3,810,000

            Sonics & Materials, Inc., a corporation organized and existing under
the laws of the State of Delaware (the "Borrower"), for value received, hereby
promises to pay to the order of the Connecticut Development Authority (the
"Authority") the principal sum of $3,810,000, together with interest on the
unpaid principal balance thereof from the date hereof until fully and finally
paid, together with all taxes levied or assessed on this Note or the debt
evidenced hereby against the holder hereof. Subject to Section 3.1 of the
Agreement (as hereinafter defined), the Borrower shall make monthly payments of
interest, the size being one-sixth of the next interest payment due under the
Indenture and monthly payments of principal or Scheduled Installments, the size
being one-twelfth of the next such principal installment or Scheduled
Installment under the Indenture. This Note shall bear interest at the rate of
interest borne by the Initial Bonds referred to below.

            This Note has been executed under and pursuant to a Loan Agreement,
dated as of December 1, 1997, by and among the Authority and the Borrower (the
"Agreement") and is secured by an Open-End Mortgage, dated as of December 1,
1997, from the Borrower to the Authority and Brown Brothers Harriman & Co. (the
"Original Purchaser") on premises located in Newtown, Connecticut (the
"Mortgage") and by a Security Agreement, dated as of December 1, 1997, by and
among the Authority, the Borrower and the Original Purchaser (the "Security
Agreement"). This Note is issued to evidence the obligation of the Borrower
under the Agreement to repay the loan made by the Authority from the proceeds of
its $3,810,000 (Sonics & Materials, Inc. Project) 1997 Series (the "Initial
Bonds"), together with interest thereon and all other amounts, fees, penalties,
premiums, adjustments, expenses, counsel fees and other payments of any kind
required to be paid by the Borrower under the Agreement and the Mortgage and the
Security Agreement. The Agreement includes provision for mandatory and optional
prepayment of this Note as a whole or in part, and in such event the prepayment
shall be credited in inverse order of principal installments due. The Agreement
further provides for the payment of interest on this Note at other rates in
certain circumstances. Advances made pursuant to Section 6.2 of the Agreement
shall bear interest at Base Rate (as defined in the Indenture), plus 2%.

            The rate of interest on this Note shall be the Applicable Percentage
of the Base Rate, determined as of the opening of business on each Interest
Payment Date (or if such Interest Payment Date is not a Business Day, on the
next succeeding Business Day), except that from and after any Determination of
Taxability (as

                                    --------
                                    SPECIMEN
                                    --------

defined in the Agreement), the rate of interest on this Bond shall be the
Taxable Rate.

            For such purpose, the following definitions shall apply:

            "Applicable Percentage" means seventy-five percent (75%); provided
that, so long as the Original Purchaser shall be the Owner of the Bond, the
Applicable Percentage may be adjusted by such owner (i) to offset any decrease
in net interest income allocable to the Bond due to a change in the portion of
its interest expense allocable to the Bond that is disallowed as a deduction
under Section 165 of the Code, or (ii) to reflect changes in federal marginal
tax rates which adversely affect the taxable equivalent yield of the Bond to
such owner. The Applicable Percentage shall be determined as of the opening of
business on each Interest Payment Date (or if such Interest Payment Date is not
a Business Day, on the next succeeding Business Day).

            "Base Rate" means the rate determined from time to time by Original
Purchaser as its "base rate."

            "Interest Payment Date" means the last day of each month, commencing
January 1, 1998, and continuing until the maturity date hereof.

            This Note shall bear interest on the overdue principal and, to the
extent permitted by law, on overdue interest at the Base Rate plus 2%.

            The Agreement, the Mortgage, the Security Agreement and this Note
(hereinafter, together with the Tax Regulatory Agreement, collectively referred
to as the "Financing Documents") have been assigned to Brown Brothers Harriman
Trust Company (the "Trustee") acting pursuant to an Indenture of Trust, dated as
of December 1, 1997 (the "Indenture"), between the Authority and the Trustee.
Such assignment is made as security for the payment of the Initial Bonds and any
Additional Bonds issued by the Authority pursuant to the Indenture.

            As provided in the Agreement and subject to the provisions thereof,
payments hereon are to be made at the principal office of Brown Brothers
Harriman Trust Company, New York, New York, or at the office designated for such
payment by any successor trustee in an amount which, together with other moneys
available therefor pursuant to the Indenture, will equal the amount payable as
principal or Redemption Price, if any, of and interest on the Initial Bonds
outstanding under the Indenture on such due date.

            The Borrower shall make payments on this Note on the dates and in
the amounts specified herein and in the Agreement and in addition shall make
such other payments as are required pursuant to the Financing Documents, the
Indenture and the Bonds. In the event of default, as defined in any of the
Financing Documents, the

principal of and interest on this Note may be declared immediately due and
payable as provided in the Agreement. Upon any such declaration the Borrower
shall pay all costs, disbursements, expenses and reasonable counsel fees of the
Authority and the Trustee in seeking to enforce their rights under any of the
Financing Documents.

            THE BORROWER ACKNOWLEDGES THAT THE LOAN EVIDENCED BY THIS NOTE IS A
COMMERCIAL TRANSACTION AND WAIVES ITS RIGHTS TO NOTICE AND HEARING AS ALLOWED
UNDER CHAPTER 903a OF THE CONNECTICUT GENERAL STATUTES, OR OTHERWISE UNDER ANY
STATE OR FEDERAL LAW WITH RESPECT TO ANY PREJUDGMENT REMEDY WHICH THE HOLDER
HEREOF MAY DESIRE TO USE. The Borrower further (1) waives diligence, demand,
presentment for payment, notice of nonpayment, protest and notice of protest,
notice of any renewals or extension of this Note, and all rights under any
statute of limitations, (2) agrees that the time for payment of this Note may be
changed and extended at the sole discretion of the Trustee without impairing its
liability hereon, and (3) consents to the release of all or any part of the
security for the payment thereof at the discretion of the Trustee or the release
of any party liable for this obligation without affecting the liability of the
other parties hereto. Any delay on the part of the Authority or the Trustee in
exercising any right hereunder shall not operate as a waiver of any such right,
and any waiver granted with respect to one default shall not operate as a waiver
in the event of any subsequent default.
